12 claims. (orso- 43) This invention relates to an improved dry shaving razor adapted to be operated by engagement with and movement relativelyto the surface to be' shaved.

It is an aim of this invention to provideV an' improved razor of the dry shaving type which wardly extending ends I2 will be manually actuated by engagement with the skin to be shaved to produce a shearing ac, tion to cut the hair from the skin.

More particularly, it is an oblect ofrthis invention to provide a stationary cylinder and a rotary cylinder mounted on said statio`nary cylinder, said cylinders being provided with slotted openings disposed at an angle to receive the hairs to be shaved, said inner cylinder being provided with sharpened edges along the opposite sides of its slots to produce a shearing action as the outer cylinder is revolved relatively to the inner cyllnder. A

Still a further object of the invention, is to provide a handle portion for said cylinders hav- ,von the handle.

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, which illustrates a preferred embodiment thereof, and

wherein:

Figure 1 is a side elevational view partly in section of the razor,

Figure 2 is a fragmentary end view in eleva- Figure 3 is an enlarged cross sectional view taken on the line 3 3 of Figure l,

Figure 4 is a side elevational view partly in sec- Figure 5 is an end view in elevation of the same,

.ing a yoke shaped head adapted to be removably Y Figure 6 is a View similar to Figure 4 of the outer, rotary cylinder,

' wherein like reference characters designate like or corresponding parts throughout the different views, I0 designates the handle of the dry shavhead II formed integral therewith and disposed transversely of one endv thereof, said head being formed of a resilient material, and having outprovided with the elongated openings I3. l

An inner cylinder designated generally as Il is provided with the reduced ends I5, formed by reducing said cylinder along its vtop and sides, the ends I5 being shaped and sized to t the openings I 3 and being removably mounted therein to rigidly'support the cylinder I4. As best seen in Figure 4, the cylinder Il is provided with aplurality of diagonallyv disposed parallel slots I6 arranged along its opposite sides forming therebetween the portions I1 which, asA best seen in Figure 3, are sharpened along their outer edges as indicated at I8 to provide cutting edges along the opposite sides of the slots I6.

A cylinder, designated generally as I9, is adapted to be rotatably mounted on the intermediate cylindrical portion ofthe cylinder I 4, said cylinder being provided with a relatively thin 'intermediate portion 20 and with the thickened tapering ends 2I The intermediate portion 2U is i provided with the transversely disposed oblong openings 22, arranged in rows around said cylinder, said openings .being disposed in staggered relationship,.as best seen in Figure 6.` VPortion 20 is provided with the outwardly projecting pointed members 23 disposed between the opposite ends vof each of the adjacent openings 22, so that each opening 22 is provided with a prong or projection 23 at each end and at each side thereof, said projections forming a serrated face adaptedto cooperate with the serrated outer face of the ends 2|, for a. purpose Wllich will hereinafter be described,

I'he opposite ends of the cylinder I9 are chamfered at 24 to engage the inwardly projecting annular beads 25 on the ends I2. The beads 25 are 'beveled on their outer sides to t the chamfered faces 24 thereby forming bearings to cooperate with the stationary cylinder Il forhrotatably mounting the -outer cylinder lI 9.

As heretofore mentioned, the yoke shaped head II is formed of a resilient material so .that the ends I2 may be sprung outwardly relatively to each other for inserting lor removing the two cyl-` inders, which are -assembled before being inserted in the head II and which may be disconnected vfrom each other after being removed from the head.

The razor is operated as follows: with the handle I0 held relatively close to the skin of the ing razor which is provided with the yoke shaped face, the roller I9 is pressed against the skin moved backwards or forwards over the skin the outer cylinder I9 willi-evolve relatively to the inner cylinder I4, on which it is mounted. The

hairs on the skin Will project through the oblong openings 22 and into the slotsIB to be sheared oil by the cutting edges I8 as the openings 22 move out of communication with .the slots IB. Openings 22, are sufficiently long so that the hairs, to be cut, will not be withdrawn therefrom before coming in contact with one of the cutting edges I8. Slots I6 are vdisposed on opposite sides of the razor, as best seen in Figure 3, so that the razor may be turned over and either side thereof used,fand both of the longitudinal sides of each of the slots I are sharpened so that the razor may be pulled or pushed or actuated by a reciprocating motion.- The hairs which are cut by the shaver will be deposited within the cylinder I4 and may' be blown out of either of the open ends 26 thereof without disconnecting the cylinders Id and I 9. The diverging or beveled ends 2I of the cylinder I9 are shaped to properly fit the contours of the human face and the angles of said portions may be varied to correspond to different general contours of the face, which may exist. Since the cylinder I9V is pressed tightly against the face, the side which is in engagement with the face will be forced lnwardly against the adjacent portion of the cylinder Il thereby forming a tight fit to insure a proper shearing cut between` the edges Il and the ends of the oblong openings 22.

Various modifications yand changes 'may obviously be made and are contemplated, as the drawing and description are only intended to illustrate a preferred embodiment-of the invention, and the right is therefore reserved to make such variations and changes; as fall within the spirit and scope of the invention as hereinafter defined by the appended claims.
